I have ditched the key barrel(golf) in my tiger and swapped it for a single throw toggle switch and a starter button.

On the barrel i had a constant live, two switched live going to the same fuse?? and a starter live....

I have wired the starter up as per instructions but have put both of the switched live wires to the single throw toggle switch.

The switch works and the button starts the car but it is now only running on 3 cylinders?? and the headlights only flash on 1 side??

What have i done?? I cannot see anything obvious

BTW 1.6 4a-ge running on an OMEX ignition.

The only likely reason I can see for the headlamp flasher to only flash on one side is one of the fuses 3 or 4 to the main beams has blown. I'm not sure what switch gear you are using for lights but if it is ford column switches you should incorporate relays to reduce the switches load or they will burn out fairly quickly.
I can't work out what the component labelled misc, down toward the bottom right of the pic is doing. If it is intended as an immobiliser it will not be sucessful as the ECU, coil and fuel pump can backfeed from fuse 6 through fuse 5 when the ignition is on. Further, when on it is an unfused supply to the ECU and engine loom.
You have taken the ignition live output wires from the ignition switch and fed them from batt+ through the toggle switch to fuse 6 and then to the 'green spider' acting as an ignition live busbar. There is a possible additional feed to the green spider from batt+ via the misc switch? to fuse 5. However if this is not a feed or not switched on it leaves the fuel pump and ecu/edis back-fed from the spider. This green spider is also responsible for supply to heater motor, wiper motor, brake light, reverse light, gauges and their senders. This is all on one 10 amp fuse or if misc is on, 2 x 10 amp fuses. Your poor running problem may just be low volts to the ECU and engine loom. I think you are heading for repeatedly blowing fuses 5 & 6 and possibly cooking your loom. Best solution IMO would be to add an ignition live switched 50amp relay to supply fuses 5, 6 and 1 direct from batt+ (and even pinch another fuse from the three fuses feeding side and fog lights) . The outputs of these fuses could then be split to the components requiring ignition live supply.
There are some bits that are not fused like the supply to the fan thermoswitch which must be a risk. Simply solved by feeding it from the output side of fuse 2. This could be further simplified by feeding contacts 85 and 30 on the fan relay from output of fuse 2, and 86 going on to the thermoswitch and through it to earth, thus activating the relay output 87 to feed the fan.
Two relays for indicators are overkill. By supplying the indicator relay terminal 49 with an ignition live and the hazard switch input with a batt+ and taking the hazard switch output to relay terminal 49, the relay output 49a can go straight to 49a on the indicator switch and the ind ign relay becomes redundant.
Is this a loom and circuit diagram supplied by Tiger? I'm sorry to appear so critical but there are many bits of it that IMO could be changed to improve safety and function.

Dusty,

Thanks for the reply. I have finally sorted it. The issue with the main beam was the fuse that i had checked

And the miss fire was cured with a new coil pack May or may not have been caused by my adventure into wiring?

I appreciate that the Tiger loom is not ideal but electrics are a black art to me so i have tried to leave it well alone.

Thanks again for the reply.
